Quorum WILLIAM HENERY HAAs, oF RAUB, INDIANA.

HOE.

To all whom t may concern."

j Be it known that' I, ILLIAM- HENERY HAAs, a citizen of the UnitedStates, residing at Raub,- in the county of Benton and State of Indiana,have invented certain new and useful Improvements in Hoes, of which thefollowing is a specilication, reference being had to the accompanyingdrawings.

This invention relates to an improved hoe or other similar implement,and has for .its primary object to provide simple and easily operatedmeans whereby the hoe blade may be adjusted to any desired angle withrespect to the handle.

It is also another object of the invention to provide a gardeningimplement having means for detachably and adjustably connecting theimplement blade to the handle so that a single handle may be used inconnection with a number of blades of Vdifferent construction to beemployed for various purposes. Y

It is also an important object of the invention to provide a veryconvenient and serviceable tool or implement of the above characterwhich is exceedingly simple in its construction, as well as strong anddurable,l and may be produced at relatively small manu* facturing cost.

With the above and other objects in view, my invention consists in thenovel features of construction, combination, and arrangement of parts tobe hereinafter more fully described, claimed and illustrated in theaccompanying drawing, in which,

Figure 1 is a perspective view illustrating the preferred embodiment ofmy improved hoe;

Fig. 2 is an enlarged longitudinal section; and

ferrule which is fixed in the end of the handle.

AReferring in detail to the drawing, 5 designates the handle of the toolor implement which is preferably constructed of wood and may be of anydesired length. This handle gradually tapers tov one end, and upon thesmaller end thereof the metal ferrule 6 is securely fixed in anysuitable manner. The wall of this ferrule, at its smaller end, isrelatively thick and provided with the threaded bore, indicated at 7,said interiorly threaded end of the ferrule projecting beyond the end ofthe handle 5.- To this Specification of Letters Patent.

Fig. 3 is a detail perspective view of thesmaller end' of the ferrule 6,a concavo-convex plate 8 is securely fixed.

1 9 designates the blade of the hoe or other implement, which, in thevillustrated embodiment of my invention, is of substantially triangularform and is provided upon one end with the teeth 10. This blade iscentrally provided with an outwardly pressed portion forming aconcave-convex projection or protuberance 11. This projection iscentrally provided with a relatively large opening 12 and the plate Shas a similar central opening 13 therein.

In the attachment of the blade 9 in the end of the handle 5, the convexface of the protuberance 11 is engaged upon the concave face of theplate 8, and a bolt 11 is engaged through the coinciding openings 12 and18 and threaded in the bore 7 of the ferrule 6. The head 15 of this bolthas a convex inner face 16 for tight frictional engagement against theconcave face of the protuberance 11. This heads of the bolt is entirelydisposed within the cavity formed by the projection or protuberance 1land does not project beyond the face of the blade 9.

From the foregoing description, taken in connection with theaccompanying drawing, the construction, manner of use, and severaladvantages of the invention will be clearly and fully understood. Itwill be apparent that by means of my device, the blade 9 may be readilydisposed in any desired angular relation to the handle 5 and thenrigidly clamped and held in place by the adjustment of the bolt 141. Anumber of implement blades may be provided for use in connection with asingle handle, said blades being interchangeable and capable of easy andquick connection to the end of the handle, or disconnection therefrom,as will be apparent.

While I have herein shown and described the preferred construction andarrangement of the several parts, it is to be understood that the deviceis susceptible of considerable modification therein and I, therefore,reserve the privilege of adopting all such legitimate changes as may befairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is:

In combination, a handle, a ferrule fixed Patented sept. 18,1917.Application med April 11, 1917. serial No. 161,367.
